Subject: [RFC v6 1/3] usb: phy: introduce usb_phy_set_event interface

From: Todd Poynor <toddpoynor@...gle.com>

usb: phy: introduce usb_phy_set_event interface

PHY drivers require a generic interface to handle per-PHY events.

usb_phy_set_event interface sets event to phy event.
PHY drivers call this interface for each phy event.
